http://librdf.org/docs/api/r3762.html >librdf_node_type librdf_node_get_type (librdf_node* node); The API docs say this returns the type of the node, does it return type information as a string? When I call following, where node is a valid node, I get a crash: *retstring = (char *) librdf_node_get_type(node); ~ Rodney
